city of New York, borough of Brooklyn, in

`the county of Kings and State'of New York,

have invented a certain new and useful Improvement in FlushingApparatus, of which the following` is a specication.l

The invention relates to means for supplying water under pressure tocloset-bowls, .urinals, and analogous apparatus, and to the constructionand operation of "the valve for controlling such supply.

The object of the invention isto provide simple and inexpensiveapparatus, easily installed, which shall be efficient The inventionconsists in certaindetails of construction and arrangements of parts tobe hereinafter described.

Similar letters of reference `indicate, like parts in all the figures.

Referringto Figs. land 2, in which a closet Y is shown operated bythedepressionofv the seat,.A is the valve-bowl, receiving its supply ofwaterthrougha nipple A at the rear, and

Bisa valve-casing-cylindrical in form screwthreaded exteriorly at'oneend, B', for attachmenttothe supply-pipe C and having an outletv B?, ,onone side adapted tobe joined to the nippleA'by a slip-jointB3 or by anysuitable connection.F B4. is a transversepartition dividing the interioryof thecasingand having a central opening blfor the passageof wal terland having a valve-seat on each face surof the` valve-stem D2..TheVrnainvalve D is. heldnormally to itsl seat` by the water-pressure andbya springf D3, abutting at one end .9o

against the rear face of the valve and at the other against aspider-frame B7, adjustably mounted in the screw-th readed interior ofthe casing at the receiving end and serving also as a sn pport for arearward extension or guide D4, of the valve-stem. A E is a hollowcylindrical cap through which the projectingendof the valvestem passes,equipped with a stung-box E',

and havinga flange EZserving to secure ayoke F toy the casing.

smoothly finished to serve as adash-pot E3, receiving a cup-leatherpiston D?, carried on the valve-stem and serving to prevent thetoo.-rapid seating of the main valve D.. The valve j is operated by abell-crank lever F', pivoted The interior of the cap is-` roo in the endof the yoke F and having onearm in contact with the projecting end ofthe valve-stem and the other acted upon by an arm G of a rocking leverG, pivotally connected to the bowl, preferably on the same hinge-rodwith the seat A2 and its cover and actuated by the depression of theseat.

The operation is as follows: The sinking of the seat depresses the leverG, correspondingly lifting the arm G, which acts upon the bell-cranklever F to force the valve-stem D2 against the tension of the spring D3,thus forcingthe main valve D from its seat and immediately thereafterseating the auxiliary valve D on the opposite side of the partition andpreventing the escape of water until the pressure is removed from thecloset-seat and the parts again move toward the normal positions. Whenthe closet-seat is allowed to rise, the spring D3 forces the auxiliaryvalve from its seat and water from the service-pipe flows freely throughthe casing and nipple A to flush the bowl. The flow continues until themain valve is again seated, the period and quantity of iiow beinggoverned by the Waterpressure, the tension of the spring D3, and theresistance offered by the cup-leather D5.

To permit the dash-pot fluid, air, or water to escape past thecup-leather, I provide a shallow groove e on the interior of thecylinder, preferably arranged spil-ally, as shown in Figs. and 4.

G2 is a leaf or plate spring attached to the lever-arm G and serving asa cushion in transferring the pressure to the valve-stem, and thusrelieving the auxiliary valve and its seat from excessive pressure. Thespring should be sufficiently stiif to transfer the pressure necessaryto move the valves in opposition to the spring D3, but with enoughelasticity to allow the closet-seat to come to rest upon the bowl whenthe pressure exceeds that required for such movement.

D8 is a cone formed on the valve-stem adjacent to the main valve D,serving to gradually reduce the area of the opening in the partition asthe valve approaches its seat, so that by the time the valve is seatedthe opening has been almost closed by the cone. I have found byexperiment that by thus gradually closing the aperture the noise due tothe hammering or chattering of the valve in coming to rest is entirelyavoided and the noise due to quickly choking off the supply is alsogreatly diminished. The groove e in the dash-pot should be of sufficientcross-sectional area to allow the valve to reach its seat in the desiredtime. This may be regulated by adjusting the spider-frame B7 inwardly oroutwardly to produce the required tension in the spring D3. By arrangingthe groove e on a slightly spiral or oblique line the danger ot chokingit by the formation of a corresponding ridge on the cupleather isavoided. The movement of the cup-leather relatively to the groove alsoperforms the important function of sweeping ciprocation.

away any particles lodged therein, and thus automatically clears thechannel at each re- Instead of a cup-leather a metallic piston may beemployed, and in such case the groove may be formed on the surface ofthe piston, if preferred, leaving the dashpot smooth.

The supply-pipe C may deliver water directly from the streetservice-pipe or other source having sufficient pressure to successfullyperform the iiushing operation; but I prefer to use a closed tank inwhich air is compressed by the water-pressu re to serve in increasingthe initial rush of water when the valve is opened. Such tank and itsconnections are shown in Figs. 5 to 11, inclusive, in which A4 is acloset-bowl, and B the valvecasing, arranged with its valve-stemvertically instead of horizontally, as in the form first described, andhaving a yoke H, in which is mounted a hand-lever II' for operating thevalve instead of the self-acting arrangement. The receiving end B of thevalve-casing is screwed into a cylindrical casting J of peculiarconstruction, which in turn is screwed into the lower portion of aclosed tank K. The casting J receives a service-pipe J', bringing waterunder pressure from the street-main or other source, and isprovided witha check-valve J2, preventing the return of the water. In thecastingJopposite to the pipe J' is a swell JS, cored to provide apassage'j, leading from an openingI on the side of the casting to theupper part thereof. The side opening receives an air-pipe J4, which mayterminate in any convenient place IOO where any drip may be ledharmlessly awayy as, for instance, within the closet-bowl-and from theupper end of the swell extends ay continuation J5 of the air-pipe,reaching vertically into the tank K and terminating a shortdistancebelow the water-line. Its upper end is slightly tapered to form a seatfor a check-valve J6, having a stem J7 guided in a yoke or frame J8,screwed upon the end of the pipe J5, as shown. The air-valve tends toclose by gravity and serves to admit air to the interior of the tank toprevent the formation of a vacuum when the main valve is opened to flushthe closet and the initial pressure of the compressed air is exhausted.By locating the air-valve below the water-line its sealing is insuredand the confined air is better held against escape, for the reason thatif the valve be not absolutely tight the leakage will be the slowpassage of water through a contracted opening instead of the rapid flowof air through a similar opening. The water thus escaping is led to thecloset-bowl or other convenient place, as above described.

J9 is an internal boss formed in the casting J, screw-threaded on itsinterior to receive the threaded end of au arm L, secured to a plate L',attached to the wall adjacent to the closet and serving as a bracket tosupport the casting J and its tank K.

IIO

The valve-casing in Fig. 7 is shown asin two portions screwed togetherand may be so constructed.

In Figs. 10 and .11 the casting J10, corre-V sponding to the casting J,is somewhat modified in shape to provide a guide J11 for Ithe valvestem, corresponding to the spiderf frame B7, and is also somewhatlengthened to provide room for the valve-seating spring when used withthe lower portion of Fig. 7 alone. This form may be found preferable insituations where space is contracted. It. also offers the advantage/ofrequiring less metal for the valve casing and casting.v

The yoke H in Figs. 5, and 7 is provided with a loop H2, in which theend of the operating-lever H is guided, and has a screw H3, by which themotion of the lever may be limited and the lift of the valvecorrespondingly determined. In this form the auxiliary valve D' isomitted. Y.

Fig. 12 shows an arrangement of pipes for supplying a number of-closetson dierent floors of a building from a single elevated tank K',receiving its supply through a casting .T12 in all respects similar tothe form shown in Fig. 6, excepting the omission of the bracket L. Theclosets on the several doors may be of the self-acting form shown inFig. 1 or that shown in Fig. 5 or may be equipped with the valve-casingset in various relations to the supply-pipe, as may be governed by theconditions of location, and operated by hand levers correspondinglymounted in yokes analogous to the yoke H, as indicated in Figs. 13, 14,and 15.

Figs. 16, 17, and 18 show the invention as applied in flushing urinals.In this form the tank K2 and casting .112 and their connections may bethe same as in Figs. 5 and 6. The delivery-pipe C2 therefrom is branchedto connect to the supply-pipes to the several urinals N N, thevalve-casings B8 B3 being connected at the point of junction. In thisform of the valve-casing I provide a swell B0,

. having facets B10, adapted to receive a wrench,.-

and the guide or spider frame B7 and spring Ds are omitted, thestuiiing-box and cupleather being alone relied on to guide the valve toits seat, aided by the cone on the valve-stem, the closing action beinginduced by the spring D9 interposed between the stuffing-box and headD10 on the valve-stem, tending to return the valve to its seat. Theushing operation is performed by pressing linward the head or buttonD10, the duration ofthe flush being determined by the action of thecupleather and the tension of the spring, as in the other forms. Fig. 19shows a similar arrangement of valve-casing adapted for service as abasin-,cock and operating in the same manner as the urinal-ush. Iclaim- 1. The combination of a valve-casing having inlet and outletopenings, a transverse partition in said casing between said openingsand having an aperture and a valveseat, avalve and its stem arranged ltobe e moved axially of said casing,a bell-crank lever carried by saidcasing' and adapted to move said valve-stem, a closet-bowl 4connected tosaid outlet-opening, a seat-lever fulcrumed on said bowl and operated bythe-depression of `a closet-seat supported thereon, arearwardly-extending arm from said seat-lever, a spring carried by saidarmand adapted yieldingly to transfer pressure from aid arm to saidbell-'crank lever. l 2.
